BOOK, PAD, AND TABLET, AND LINE RULER THEREFOR Filed Sept. 26. 1950 IINVENTOR W 54 k I BY a M I A TTOR/VEY Patented Mar. .14, 1933 PHILLIP H.KAI TFMANN, OF CLEVELAND HEIGHTS, OHIO 300x, PAD, Aivn TABLET, AND LINERULEB, rn'nnnron Application filed September 26, 1930. .Serial No.484,604.

This invention relates to devices for ruling, lines upon the sheets ofnotebooks, pads,

and tablets, and more particularly to devices of. this character whichare incorporated with and form a part of such a book or tablet. Theapplication is a continuation 1n part of my application N 0. 140,7 51,filed October 11, 1926, now matured into Patent No.

It is the'general purpose and object of the invention to provide, fornotebooks, pads and tablets, a device which is capable of being combinedor associated therewith, preferably as a cover member,and which devicewill enable lines to be ruled'rea-dily and conveniently upon the sheetstherebeneath and at varying distances apart from the margins ofsuchleaves.

Further and more limited objects of the invention will appearhereinafter'and will be realized in and through the constructionand'arrangement ofparts shown in the. drawing hereof, wherein Fig; 1represents a per-' spective View ofa tablet having my inventionincorporated therewith; Fig. 2 a View in. end elevation of a notebook ofthe looseleaf bindertype in which my invention is incorporated; and Fig-3 a view, similar to Fig. 1, showing another form of notebook of theloose-leaf binder type in which my invention is incorporated;

Describing by reference characters the parts shown in the drawing, andfirst with particular reference to the form shown in Fig. 1, Arepresents a stack of superposed leaves, each'leaf having its sides andone end free and having its opposite end secured to corresponding endsof the other leaves in a manner usual in the construct-ion of tablets,as by means of an adhesive uniting such ends. Each leaf may, if desired,be provided with lines A extending longitudinally thereof and parallelwith its sides. For

the purpose of ruling lines transversely of* the sheets of the pad ortablet, I have provided a transverse-line ruler, which is indicatedgenerally at B and'which is shown as connected to the top of the tabletby a channel-shaped binder C, secured as by an adhesive to the end ofthe ruler, to the correwith a sponding end of the pad or tablet, and tothe bottom ofthe lowermost sheet 'of the pad ortablet. Thecombined coverand lineruler B comprises preferably twoplies of material, the outer orfoundation ply B 'being of tough pliable material, preferably paper, andthe inner ply B which is secured'to the outer plyas by an'adhesive,-being preferably made of blotting paper; The I combined coverand line ruler'B is provided plurality of folding lines or hinges B thesaid folding lines or hinges being preferably parallel with each-otherand iv ex tending transversely of the tablet and constituting, when thecover is folded back thereon, straight edges for the purpose; ofrulinglines upon the sheets A therebe'nealth.v

The folding lines or hinges in this case are conveniently formed byscoring the inner the'purpose of ruling lines at any desired 5 distancefrom the ends of the. sheets A therebeneath; The scorings abovedescribed are hereinafter referre-d'to as score lines. 7

It will be obvious that, by the construction shown and described, I haveprovideda.tab--.

let with an attached line ruler which. serves the triple functions of aline ruler, ablotter,

and a cover.)

In Fig. 2 1 have shown a modification of the'invention shown in Fig. 1'wherein che line ruler D is preferably formed in the same manner as theline ruler B, consisting'ofa foundation p-ly D,-'preferablyoftough,.pliable paper, and a lower. ply D preferably'of blotting paper,adhesively united to the r foundation ply and provided'withi thefolding'line or hinges D As will appear from Fig. 2, the combinedpad'and line ruler will be provided at one end with. apertures E which,in the form of my invention shown inFig. 2, are adaptedto receivetherings F carriedby the back F of the loose-leaf binder, the covers ofwhich are indicated'at F In Fig. 3 therev is shown another form of looseleaf binder, with which my invention:

B may be folded along any 1 p is incorporated. In the embodiment of myinvention shown in the said view, A denotes a stack of leaves whichconstitutes a filler for the loose leaf binder which comprises anintegral upper cover G and lower cover G united by the back G Openings Gare provided through the covers G, G adjacent to the back G and throughthe corresponding end of the filler, the filler being secured in placewithin the loose leaf cover by the rings G In the constructionshown inthis view, the upper cover G constitutes a line ruler, the lower surfaceof such cover being provided with the folding lines G extending upwardlythereinto from the lower surface of the cover, the folding lines beingconveniently formed by cutting nearly through the .cover from the bottomto the top thereof.

In this embodiment of my invention, the

upper cover of the loose leaf binder constitutes a llIlG IIllBI for anysuccessive numbers of fillers. I

In all of the forms of my invention, the line ruler is so, associatedand connected with ,the stack of leaves therebeneath as to enable linesto be quickly and conveniently ruled 'upon successive leaves of suchstack byfolding the rulerybackward upon itself in the manner indicatedin Fig. 1.

Furthermore, while I prefer to combine theline ruler with a blotter andto form the .folding lines by cutting through or partly .through theblotter member, I do not limit myself to this manner of constructing the-lineruler, but only in accordance with the spirit and scope of theappended claims.

' j Having thus described my invention, what .I claim is: 1 A line rulercomprising a sheet provided. with spaced narrow, line-like, relatively---weak .areas extending thereacross for facilitatingbending, thedistance between said areas being great relative to the widththereprovided with spaced narrow, line-like, rela tivelyweak areasextending thereacross for facilitating. bending, the distance betweensaid areas being great relative to the width thereof.
